In a review of the cell biology and heredity studies of 1900–1910, Bernardino Fantini argues that the choice of an experimental subject or organism was crucial in opening up new discoveries and new theories for specific fields of research.69 Thinking on a broader level, Bütschli expressed a similar view when he stated that an understanding of the true nature and structure of the “elementary organism” was crucial to the whole of biology. In this article we have traced the impact of (...) Bütschli's unicellular model of protozoa up to the general acceptance of the eukaryotic cell as nature's primary organism. We have also seen that Bütschli's vision in the Studien gave birth to Protistenforschung and Zellforschung, sister sciences whose task it was to further and integrate knowledge of the living cell. Of necessity, we have confined ourselves to German scientific developments. However, our attempt to recapture and define the unity and meaning of a biology of the “cell-microcosm” has given us pause to reconsider the development and nature of Wilhelmian biological science.

This paper examines relations between eugenics and genetics during the Weimar Republic. Research aims and requests for funding were motivated by a sense that biology could contribute to national reconstruction after the First World War. Geneticists' participation in social policy-making is assessed, as well as the rise of interest in eugenics and racial biology among public health officials. It was important that eugenics be acceptable to the Centre Party, and a sometime Jesuit, Hermann Muckermann, took a leading role as intermediary (...) between the state and human geneticists in the founding of the Institute for Anthropology, Human Heredity and Eugenics. Earlier plans to establish a national institute, the organization of the Institute as it actually materialized, and the scope of research are considered. Finally, the dislocation in 1933 is assessed in order to further emphasize how the Institute was deeply embedded in the Weimar social structure. (shrink)
